Patent CA-2203098-A1 (CA)
Title: Procede de preparation d'un echantillon dans un capillaire de scintigraphie pour une recherche par immunofluorescence
Inventor: DUBROW ROBERT S
IPC: G01N15/14
Filed: 1995-09-22
Abstract: Méthode et mélange d'échantillons pour l'énumération par fluorescence de composants cible colorés d'un échantillon de sang total, utilisant un instrument d'imagerie. Le procédé de préparation de l'échantillon garantit que la quantité de composants cible par unité de volume de sang total est préservée par l'élimination de certaines étapes de préparation non quantitatives, tout en produisant une couche d'hématocrite régulière dans le capillaire de scintigraphie. Pour empêcher l'agrégation des globules rouges, on ajoute un réactif à une partie aliquote de sang total. La partie aliquote de sang total est mélangée avec une quantité présélectionnée d'un complexe de colorant fluorescent et de ligand, lequel marque les composants cible (par exemple les antigènes de surface CD4 et CD8 sur les leucocytes). On laisse l'échantillon et le complexe fluorescent incuber pendant une durée suffisante pour lier suffisamment le complexe fluorescent aux composants cible, afin d'obtenir un signal de fluorescence de la cible que l'on puisse distinguer du signal fluorescent du complexe fluorescent non lié de l'échantillon. Le mélange résultant permet à l'instrument d'imagerie de détecter des pics d'intensité de fluorescence provenant des composants cible, et donc d'effectuer une énumération volumétrique des composants cibles avec un degré amélioré de précision et d'efficacité.

Patent CA-2225873-A1 (CA)
Title: Active/standby routing system on atm network
Inventor: MASUO HITOSHI
IPC: H04L12/70
Filed: 1997-12-29
Abstract: In an active/standby routing system for establishing a active route and the corresponding standby route in an ATM network, a node transmits, as a connection signaling message,  a connection pair identifier which is unique to a combination of the active and the standby routes together with information which is indicative of either of active and standby routes. The active and the standby routes are quickly switched from one to another even when one of the routes is to be recalculated due to a trouble in the other route.       The connection signaling message is transmitted to both the active and the standby routes from the first node.  A repeating node receives the message, sets the route indicated by the information indicating an active or standby route in the received message and thereafter transmits the message. An end node records information on paired active and standby routes from the connection signaling message received through the active and standby routes to maintain correspondence between active and standby routes.
Patent CA-2226005-A1 (CA)
Title: Snap-in proximal connector for mounting an optic fiber element into a light source system
Inventor: ROLLER THOMAS W
IPC: G02B6/42
Filed: 1996-07-12
Abstract: The proximal connector (22) includes a stainless steel cone-shaped (32) ferrule (30) enclosing a proximal end of the optic fiber element. The ferrule is inserted within a matching aperture of a receiving block (26) which is also made of stainless steel. The matching shapes of the ferrule and the aperture of the receiving block ensure effective heat transference from the ferrule into the receiving block. Both ferrule (30) and the aperture (24) are axially symmetric such that any rotation of the proximal connector while inserted into the receiving block does not change the location of the entrance aperture of the optic fiber element. The proximal connector also includes a case (34) having an indented ring (36). A ball plunger biasing mechanism (42) is mounted within the aperture (24) of the receiving block and is positioned for engaging with the indented ring only while the proximal connector is fully and securely inserted within the aperture. The plunger prevents accidental removal of the proximal connector while also providing a biasing force for ensuring solid contact between the cone-shaped ferrule and the corresponding portions of the receiving block to further facilitate the heat conduction.

Title: Device and method for checking the geometry of a hole bored in a part
Inventor: GUERIN SYLVAIN
IPC: G01B11/03
Filed: 1996-09-25
Abstract: A sensor arm (1) is inserted into a hole (3). The arm is mounted on a pivot (5) perpendicular to the arm axis so that it may be urged into engagement with the wall of the hole, e.g. by an air cylinder (12). The pivot (5) is in turn rotated about an axis passing through the hole, preferably by means of a rotary body (10).  A bearing piece (16) controlling the sensor arm may be moved towards or away from the hole and rigidly supports a light sensor (8) that receives a light beam (7) from the sensor arm. The geometry of the hole is determined on the basis of the position where the light beam impinges on the sensor and the position of the bearing piece relative to the hole.

Title: Locking structure for securing a fluid transfer tube
Inventor: TEGELER GARRY R
IPC: F16L33/28
Filed: 1998-04-03
Abstract: A test sample card is provided with a locking feature for achieving a positive, locking engagement with a transfer tube that conducts fluid into the interior of the test sample card. The locking feature consists of a tubular channel inwardly disposed from the fluid intake port that has an inner annular rim defining a restriction. The annular rim is of a reduced diameter relative to the diameter of the transfer tube. A recessed region is positioned inwardly from the restriction that has an opening in one of the surfaces of the card body. When the transfer tube is inserted into the tubular channel, the first end is forced past the restriction into the recessed region, with the annular rim compressing the transfer tube. The user is able to sense with their hands when the first end is inserted past the restriction. Visual observation of the first end of the transfer tube through the opening in the card surface confirms that the transfer tube has been properly inserted into the test sample card.
